Identification of strategic points for the construction of lakes or reservoirs in the Las Cañas hydrographic unit, municipality of Boaco, Nicaragua

Abstract

The present study was carried out in the Las Cañas hydrographic unit, located in the municipality of Boaco, Nicaragua, according to the data obtained in the monographic research study entitled “Proposed territorial planning plan in the Las Cañas hydrographic unit”, the communities have drought effects due to the natural condition of being part of the area where there is a lack of rainfall, also known as the dry corridor of Nicaragua and sometimes with greater effects, due to climate variability and the manifestation of the climate phenomenon “El Niño” (ENOS), water is limited for human and animal consumption and even water is not available for irrigation, reason why in this study the identification of strategic points for the creation of reservoirs was carried out and for this the geomorphology was used, from this the Intramontana Plain and the Maizama Plain were selected, another important variable to be taken into account is the texture of the soil selecting the heavy clay for being this impermeable, with respect to the water network the seasonal rivers and extended water network were chosen, the rainfall variable is considered the availability of precipitated water which is, according to historical records considered, 1200-1600 mm for the sub humid zone and 800 1200 mm for the semi-dry zone, from all these selected variables are the optimal conditions to build reservoirs in the selected sites, this means that the basin has the potential to collect water by collecting precipitated water, for irrigation, animal consumption and fish farming development.
