Models Have Evolved Since The Turn Of The Century Subirrigation increased AET for all values of K (Parsons 1987). water TABLE managEMENTand soil NITROGEN LOSS. J. of Agric. water manag., 32 (1997)239-258. http://www3.bae.ncsu.edu/bae572/ricks/Modeling Paper.htm
Extractions: Models have evolved since the turn of the century. There are models for most any item or system that exists. Developments in mathematics have enabled the world of models to explode. Now most everything can be modeled using some sort of mathematics. Agriculture is field that must rely on predictions. The Farmers Almanac is a source of information that allows one to predict upcoming events. The data in the Almanac is used to model events, especially hydrologic events that can occur in the future. The models that are created today are complex and involve numerous computations that only a computer can do. These models are used in a wide variety of tasks. Models have long been a vision to people, now they are a reality, and have been used to create systems that produce cost-efficient and effective answers to everyday problems. As with life, models come with restraints. These constraints must be weight to see the proper give and take ratio to ascertain a compatible model. There are numerous restraints exist among modeling. The obvious is the budget of the project. The more money available, the precision of the model increases. The use of complex mathematical relationships with multiple iterations leads to the need of vast amounts of computer time. The trade off is the computer time and cost is marginal compared the salary of an individual that is capable to do these mathematical computations. Educated personnel with extensive knowledge and understanding of the model are necessary to determine if the data created makes sense. Finally a model is of no use if there is not real world data to simulate. Simulation of this data checks the validity of the model and aids in its marketability (Johnson 1973).

D.S. Thakur - Experiments In Hill Agriculture - Irrigation Experiments in Hill Agriculture irrigation, soil and water Conservationand watershed Development for Rainfed Agriculture, by DS http://beaskund.helloyou.ws/kullu/agriculture/a1007m.html
Extractions: Regional Research Station, Bajaura Provision of irrigation, soil and water conservation and watershed development are necessary for sustainable agriculture. To save and conserve soil and water are to save life on earth. Therefore, to promote ecological and sustainable farming, provision of cheap water harvesting and storage tanks for irrigation, check dams, earthen cum stone field bounds and boundaries, conversion of outwardly slopping terraces or fields into inwards slopping fields, fuel-fodder grasses, tree plantations and afforestation for soil and water conservation on watershed basis have beeb taken up and continued on a large scale. Irrigation is the most important factor and input for the development of sustainable agriculture system, as it increases the efficiency of all other inputs too. Therefore, all sources of irrigation like rivers, streams, nullahas, springs, rainwater, etc. should be fully tapped, harvested and developed. Once irrigation becomes available, it is necessary to make changes in cropping patterns, cropping systems and cropping intensity by including more remunerative high value crops and the IIHFS. To increase the efficiency of irrigation, more efficient methods like sprinkler and drip irrigation must be used.

Extractions: Since 1986, IWMI has been working in Nepal to promote optimal use of the countrys water resources through collaborative research and institutional development activities. IWMI provides research-based recommendations on water policy to the government of Nepal, technical support to state and national programs, and opportunities for training to local researchers and resource managers. In 1994, IWMI and the Kingdom of Nepal signed a memorandum of understanding formalizing IWMIs role in helping the country productively manage its water resources. IWMIs work in Nepal is guided by the IWMI Nepal Consultative Committee, which is composed of policy makers, implementers, and representatives from academic institutes and research agencies. Until 1995, IWMIs Nepal office was managed by an internationally-recruited staff. Currently IWMI operates primarily in a nonresidential mode, with researchers from headquarters managing and providing input to projects. The Department of Irrigation has provided the Institute with office space, and nationally-recruited staff is stationed there. IWMI gratefully acknowledges the Ford Foundation, the Department for International Development and the Asian Development Bank for their support of the Institutes work in Nepal.

Wiley, New York. METHODOLOGY RESULTS AND DISCUSSION FUTURE PROSPECTS REFERENCES ... Table 1 Guayule ( Parthenium argentatum Gray) is a promising alternative to rubber tree ( Hevea brasiliensis Muel. Arg.) for production of natural rubber in semiarid regions of the world. For the United States, which is totally dependent on foreign sources of natural rubber, developing guayule as a commercial crop should be a high priority. A domestic source of natural rubber is vital to our national defense and helps balance the budget by reducing the one billion dollars spent annually for the imports of Hevea rubber from southeast Asia. Salt-tolerant guayule cultivars are needed for economic production of rubber on marginal lands and in areas with low quality saline water. The available guayule germplasm which is being used to develop new guayule cultivars are 2 n = 36, 54, or 72 (Bergner 1944, 1946; Stebbins and Kodani 1944). Plants with 2
Extractions: Potsdam Institute for Climate Impact Research, Telegrafenberg, 14412 Potsdam, Germany The new watershed model SWIM (Soil and Water Integrated Model is a continuous-time spatially distributed simulation model for mesoscale watersheds. The model is under develpment in the framework of the RAGTIME ( R egional A ssessment of G lobal Change Impacts t hrough I ntegrated M odelling in the E The model runs under the UNIX environment. A comprehensive three-level scheme of watershed disaggregation into subbasins and hydrotops (a hydrotop is a set of disconnected units in the subbasin, which have a unique land use and soil type) combined with reasonable restrictions on subbasin size should allow the applicability of the model to be extended to larger basins. The time step for the model application is daily. The SWAT/GRASS interface (Srinivasan, Arnold, 1993) is adopted for SWIM to extract spatially distributed parameters of elevation, land use, soil types, and groundwater table. SWIM integrates weather, hydrology, erosion, crop growth, and nutrients (nitrogen, N and phosphorus, P) at the watershed scale. The following hydrological processes are included:
