Abstract
Rainwater harvesting is an effective method for the utilization of surface water resources in different regions. Since the impervious surfaces have noticeable potential of rainwater harvesting, designing and planning in order to collecting of rainwater is a suitable solution for adapting of water shortage in many places.In this study, in order to achieve the research objectives in various sections related to runoff and food surveying in the selected area, several methods will be used, each of which has its own stages. In order to calculate runoff, the average annual rainfall information in the study area was taken from Shahrekord synoptic station. Then, according to the announced relationships, we estimate the amount of runoff in the basin. To analyze the water requirement of crops and horticultural products using the method proposed by the Journal of the World Food Organization (FAO) using statistics and meteorological information and field studies related to the crop calendar and different stages of plant growth, evaporation parameters and potential transpiration of the plant standard level (ETO) Which is the evaporative power of air is estimated and then introduced by introducing the plant coefficient (Kc) according to the type of plant, stage and length of growth period and its effect on (ETO), plant evapotranspiration (ETc). The results of data analysis related to optimal water consumption, increasing crop and horticultural cultivation (studied: Noabad village, Chaharmahal and Bakhtiari) based on the objectives and research questions have been presented and discussed. First, the amount of runoff from rainfall in the study area was calculated. In the next section, the water needs of the dominant agricultural and horticultural products in the village were calculated. Depending on the amount of runoff from rainfall and the water requirement of each product, it can be used to cultivate more crops using the resulting runoff for optimal water use.With 3/243486 cubic meters. Then, according to the calculations of runoff and water requirement of the plants in the study area, practical scenarios are presented in this area.
