In this study, the quantitative zoning is used to identify areas suitable for artificial recharge in the mountainous area of Gohar and Garbayegan plain, Fars province fitting a linear fundamental form to the surface. The structures with grade two for triplex windows and the data from the digital elevation model with a resolution of 10 m was used to determine the best fitable fundamental structure. The sum of square differences of the surface differences is used as an indicator to determine the degree of fitting the fundamental structures. By fitting the interpretable patterns to the Earth's surface it can be determined that the earth was similar to what pattern and formation mechanism. Mountain ranges upstream alluvial cones and plains located downstream of the upstream alluvial cones are not linear levels. Places which are not at the acceptable slope (gradient less than 0.002 and higher than 0.1) allocated to the zero fitting degrees and the fitting degree values are positive in alluvial cones and areas fall in the acceptable range of the slope. The results show that the surfaces located downstream of the alluvial cones and the plains are most suitable areas for floodwater spreading in the Garbayegan watershed.

The basis of land management is the geomorphological zoning of the land surface, which is determined based on the same geomorphological characteristics of the zoning. Ground zoning detect land features by basic surface features such as height, slope, and slope direction. In this study, quantitative zoning of the land surface with small coefficients to the surface has been used to identify suitable areas for artificial feeding in the mountainous region of Gohar and Dasht-e Gorbayegan in Fars province. Quantitative zoning of the land surface has been performed by Evans-Shri coefficients due to the accurate determination and separation of types, faces, and surface features of the land has an important role in determining the exact land use. In this research basic models included linear, circular, and divergent models. These basic models with the dimensions of the final windows are ranked second in the MATLAB software to the level the ground is fitted to determine the fit of these models, the parameter of total squared difference has been used. In addition, the suitability of the study area for flood distribution in five different classes was determined using fuzzy logic. The most suitable areas for feeding downstream of the cones had five parameters with a maximum score of 20. The inappropriate class related to the lower plains of alluvial fans have a minimum score of five input classes in fuzzy logic, which is equal to zero.
