  • Uneven distribution pattern of monsoon rain and highly permeable soil type and poor rainwater management practices effect the crop yield. Also lands remain barren in winter season due to lack of rainfall. A Dynamic Programing (DP) model is developed to allocate optimum supplemental irrigation to crop for receives maximum net annual return from the cropped area under land and water availability constraints in the OFR based rainfed agricultural system.

  • Sediment Transport in Aquatic Environments is a book which covers a wide range of topics. The effective management of many aquatic environments, requires a detailed understanding of sediment dynamics. This has both environmental and economic implications, especially where there is any anthropogenic involvement. Numerical models are often the tool used for predicting the transport and fate of sediment movement in these situations, as they can estimate the various spatial and temporal fluxes.

  • In order to permanently preserve the quality of habitat for bird species resident to the Weidmoos, it was essential to alter the post-extraction state of the site, so that an open landscape with numerous bodies of water and moist areas would remain. The most important measure to ensure the long-term conservation of the Weidmoos as an open landscape – and therefore as a valuable bird habitat – is the so-called “re-waterlogging” of the site.

  • Water scarcity has many negative impacts on the environment, including lakes, rivers, wetlands, and other fresh water resources. Furthermore, water shortage makes flow management in the rehabilitation of village streams problematic. Owing to poor water resource management system and climate change India faces a persistent water shortage. Indian agriculture accounts for 90% water use due to fast track ground water depletion and poor irrigation systems. Water is a critical input into agriculture in nearly all its aspects having a determining effect on the eventual yield.

  • Vegetation Cover in Rawdat Norah was estimated to be 0.635 Km 2 or 16.2% of the total area of the Rawdat which is 3.924 km2 . The main dominant vegetation is Rhazya strica. Some morphometric properties and the characteristics of the watercourse system affecting the capacity of the Wadi Al-Atsh watershed to transform rainwater into surface runoff water had been determined. Accordingly, the drainage area of Wadi Al-Atsh has been calculated and found to be 13899.7 km2 , where the watershed length reaches 170.9 km, and the average width of Wadi Al-Atash watershed also reached 81.3 km.
