Papers People. Agricultural water productivity assessment for the Yellow River Basin. Agricultural water productivity WP has been recognized as an important indicator of agricultural water management. This study assesses the WP for irrigated WPI and rainfed WPR crops in the Yellow River Basin YRB in China, water management essay.
WPI and WPI and WPR are calculated for major crops corn, wheat, rice, and soybean using experimental, statistical and empirically estimated data. The spatial variability of WPI and WRR is analyzed with regard to water and energy factors. Results show that although irrigated corn and soybean yields Save to Library, water management essay. Methodology to explore interactions between the water system and society in order to identify adaptation strategies, water management essay.
Development of sustainable water management strategies involves analysing current and future vulnerability, identification of adaptation possibilities, effect analysis and evaluation of the strategies under different possible futures Development of sustainable water management strategies involves analysing current and future vulnerability, identification of adaptation possibilities, effect analysis and evaluation of the strategies under different possible futures.
Recent studies on water management often followed the pressure-effect chain and compared the state of social, economic and ecological functions of the water systems in one or two future situations with the current situation.
The future is, however, more complex and dynamic. Water management faces major challenges to cope with future uncertainties in both the water system as well as the social system. Uncertainties in our water system relate to changes in drivers and pressures and their effects on the state, like the effects of climate change on discharges.
Uncertainties in the social world relate to changing of perceptions, objectives and demands concerning water managementwhich are often related with the aforementioned changes in the physical environment. The method will be used for scenario analysis and to identify social responses including changes in perspectives and management strategies, water management essay.
The scenarios and responses will be integrated within a rapid assessment tool. The purpose of the tool is to provide users with insight about the interaction of the social and physical system and to identify robust water management strategies by analysing the effectiveness under different possible futures on water management essay physical, water management essay, social and socio-economic system. This method allows for a mutual interaction between the physical and social system.
We will present the theoretical background of the perspectives method as well as a historical overview of perspective changes in the Dutch Meuse area to show how social and physical systems interrelate. We will also show how the integration of both can contribute to the identification of robust water management strategies. Methodology to determine the vulnerability of deltas to climate change water management essay to identify adaptation strategies. Recent studies on water management often followed the pressure-effect chain and compared the state of social, economic and ecological functions of water systems in one or two future situations.
The future is, however, water management essay. Sustainable water management under climate change, water management essay. How water management essay develop strategies for an uncertain future. Sustainable water management involves dealing with uncertainties, both now and in the future.
Uncertainties are a fact of life: the further ahead, the more difficult to address. Uncertainties for future water management manifest Uncertainties for future water management manifest themselves in several ways. Prediction of backwater level of bridge constriction using an artificial neural network. Bridge constriction in channels usually increases the water level well above the normal depth and may result in overflow on the surrounding floodplain.
In this paper, the experimental backwater level water management essay which the maximum afflux value was In this paper, the experimental backwater level at which the maximum afflux value was observed due to bridge constriction was investigated. A multi-layer Water quality modelling to support the operation of the Kakhovka Reservoir, Dnieper River, Ukraine, water management essay.
A note on uniform open channel flow in circular pipes. Stochastic programming in water management: A case study and a comparison of solution techniques. Abstract The present stage of developments in stochastic programming gives already a good base for real-life applications. The possibility of using alternative models is studied on a small-size but meaningful example connected with water The possibility of using alternative models is studied on a small-size but meaningful example connected with water management of a real-life water resource system in Eastern Czechoslovakia, water management essay.
Both of the considered conceptually different stochastic programming models take into account intercorrelations within a group of random parameters and provide comparable optimal decisions. At the same time, these models Hydrological Conditions Control P Loading and Aquatic Metabolism in an Oligotrophic, Subtropical Estuary. Page 1.

Evapotranspiration of a Mid-Rotation Loblolly Pine Plantation and a Recently Harvested Stands on the Coastal Plain of North Carolina, U. Hydraulic Redistribution of Soil Water in a Drained Loblolly Pine Plantation: Quantifying Patterns and Controls over Soil-to-Root and Canopy-to-Atmosphere Interactions.
The conversion of wetlands to intensively managed forest lands in eastern North Carolina is widespread and the consequences on water and carbon balances are not well studied. Quantification of evapotranspiration ETtree transpiration Quantification of evapotranspiration ETtree transpiration and their biophysical regulation are needed for assessing forest water management options.
We characterized vertical variation in the diurnal and seasonal soil volumetric water content at 10 cm intervals to evaluate changes in water availability for root uptake and monitored eddy covariance ET and water management essay transpiration sap flux in a drained Loblolly pine Pinus taeda L, water management essay. We also quantified the magnitude of water management essay redistribution HRthe passive movement of soil water from deep to shallow roots, to identify factors affecting the seasonal dynamics of root water uptake, root and plant water potentials and stomatal conductance.
Soil water content varied with soil depth and total water use from the upper 1m peaked between 4 and 6. After periods of more than 10 days without water management essay, water extraction shifted to the deeper layers, and recharge from HR approached 0. We propose that HR prevented predawn water potentials from decreasing during periods of increasing soil water deficit, therefore maintaining a constant driving force for water uptake of around 1.
It was thought that HR was an important mechanism for maintaining shallow root function during drought and preventing total stomatal closure but our study shows water management essay even in wet conditions with soil water potentials never dropping below This first approximation of the extent of HR in this ecosystem suggests that it is likely to be an important process in wet forests of North Carolina. Uptake and Hydraulic Redistribution of Soil Water in a Natural Forested Wetland and in two Contrasting Drained Loblolly Pine Plantations: Quantifying Patterns over Soil-to-Root and Canopy-to-Atmosphere Water management essay.

Located on the Swiss-Italian border, lake Verbano is a natural lake used as multipurpose reservoir. The main objectives of its management are the satisfaction of downstream water supply for hydropower gen- eration and irrigation, water management essay The main objectives of its management are the satisfaction of downstream water supply for hydropower gen- eration and irrigation, the control of floods and the protection of environmental quality.
Since these objectives are conflicting, each stakeholder has suggested a way to solve his own problem. Ambiguity: the challenge of knowing and deciding together. How can models better aid the decision processes for the management of water resources? Despite the long history of development and use of models in policy making, there is still a poor integration between modeling and the decision process.
