Development of soil and water resources through flood spreading systems is one of the accepted
methods in water resources engineering and management. At the time being, 35 flood spreading stations
constructed in Iran, and covers about thousands villages and a million hectares of the flood area.
Expenditure of the operation and maintenance of such a modern systems is a main constraint for the governmental
management agencies. Hence, dissemination of this modern system is restricted among local
communities. Evaluation of these systems is the main objective of this explanatory research in Kashmar
flood spreading station. The necessary data and information were collected and achieved by reviewing the
secondary data, field survey and conducting workshops through Participatory Rural Appraisal (PRA),
Rapid Appraisal (RA) and Participatory Diagnoses (PD). The results of this research showed that within 8
years of operation of this system, only 5% of the project area were covered by flood and the rest of spreading
area remained unused. Therefore, as an economic aspect, it can be said, although the B/C is more than
1.14, the construction of such a huge system is not accepted. The benefit of groundwater recharges (more
than 5 billion Rials over 8 years period) is too high in comparison to others outputs (lese than 0.4 billion
Rials). These results show if we focus on limited objective (groundwater recharges only), it could be a solution
for reduction of mentioned constraints.
