Information is provided about the approach and experience in flood management in the Damodar river basin of India. This is achieved through a scheme for the integrated operation of a number of reservoirs on that river and on its tributaries for the purpose of irrigation, hydropower generation and flood protection. Of particular interest is the recent change in policy towards a multi-disciplinar...

The water use efficiency under conventional flood method of irrigation, which is predominantly practised in Indian agriculture, is very low due to substantial conveyance and distribution losses. Recognizing the fast decline of irrigation water potential and increasing demand for water from different sectors, a number of demand management strategies and programmes have been introduced to save wa...

Three models were evaluated for their accuracy in simulating pesticide runoff at the edge of agricultural fields: Pesticide Root Zone Model (PRZM), Root Zone Water Quality Model (RZWQM), and OpusCZ. Modeling results on runoff volume, sediment erosion, and pesticide loss were compared with measurements taken from field studies. Models were also compared on their theoretical foundations and ease ...

Most structural and some nonstructural water projects require significant sunk costs and lead to uncertain economic and ecological outcomes. For instance, building irrigation or flood control dam requires sizable sunk cost, an investment that is difficult to recover later. The dam faces uncertainties in terms of future rainfall, the performance of the dam’s structures and downstream levees, the...

Dehydrogenase and catalase activities were measured in a Eutric Histosol irrigated with municipal wastewaters (Lublin, Poland) purified by a two-step (mechanical and biological) treatment. Soil enzyme activity was used to test the biochemical status of the soil-plant system, the last step of wastewater purification. Three experimental fields, each of 1 ha area, were planted with Populus nigra, ...

2011 Thailand flood has brought serious impact to downstream of Chao Phraya River Basin. The flood peak period started from August, 2011 to the end of October, 2011. This research focuses on midstream of Chao Phraya River Basin, which is Nakhon Sawan area includes confluence of Nan River and Yom River, also confluence of Ping River and Nan River. The main purpose of this research is to understa...

Effective and efficient irrigation practices are critical to successful rice production and to the sustainability of rice production. To better understand how to address the issue of water management in rice we initially installed water flow meters on two studies that were designed to evaluate disease incidence using fertility, variety/hybrid, and water management as treatment variables. One st...

Soil moisture monitoring and the characterization of the spatial and temporal variability of this hydrologic parameter at scales from small catchments to large river basins continues to receive much attention, reflecting its critical role in subsurface – land surface – atmosphere interactions and its importance to drought analysis, crop yield forecasting, irrigation planning, flood protection, ...

The farming of natural flood plains was in many parts of the world the cradle of civilization. The Nile Valley, the Indus Valley and Mesopotamia supported high cultures with complex social structures. These gradually harnessed and changed their own environment into what we often call a Constructed Social-Ecological System – or irrigation systems. The distinct path of development from natural ri...
