“…This is because of the high frequency of heavy rains and the vulnerability of the hydrological basins due to changes in land cover [14]. The current technological development and the use of hydraulic modeling to generate hydrological hazard scenarios have allowed to define those areas with high flood risk for different cities in Mexico [40][41][42][43]68,69]. In this work, the Hec-Ras software was used to identify zones in the urban area of the municipality of Yautepec that will be affected in the future by river overflow for different return periods.…”

“…Besides, the combined use of the Hec-Ras model and geographical information systems (GIS) is the perfect tool to generate scenarios of hydrological hazard and flood risk for urban areas [31][32][33][34][35][36][37][38][39]. Hydraulic modeling to generate hydrological hazard scenarios due to river overflows in urban areas is widely used [40][41][42][43].…”

The hydrological hazard for the municipality of Yautepec de Zaragoza, State of Morelos, Mexico, is evaluated considering the overflow process of the rivers located in the Yautepec sub-basin. Different scenarios of hydrological hazard were generated to identify those areas with high flood potential using hydraulic modeling for three return periods (Rp) of 50, 100 and 500 years based on statistical analysis of the maximum annual discharge of the Yautepec hydrometric station. We used the Hec-Ras software and geographic information systems (GIS) to model the different flood scenarios. Our results indicate that 10% (1.5 km2) of the total urban area of the municipality will be flooded for a return period of 50 years. About 12% (1.8 km2) of the territory will be affected by flood for a Rp of 100 years. For a Rp of 500 years, approximately 13.5% (2.1 km2) of the municipality’s area will be flooded. Spatially, the central and southern regions of the municipality will be affected by flood heights greater than 1 m for Rp of 100 and 500 years. The northern zone will have heights of less than 0.50 m for Rp of 50 years. Our results can be used as a tool to prevent and reduce the impact of future floods in the municipality of Yautepec de Zaragoza.

“…Although this state is not frequently achieved in natural environments (Harwood et al, 1999), the oases function as a very efficient hydraulic system, due to the relative abundance of water that accumulates in the springs, rivers, plains, and basins (Díaz and Troyo, 1997). For example, it is known that the springs that feed the Comondú oasis can provide water to the oasis ecosystem over many dry years and can also accumulate water in flood areas in the lower and upper parts of the basin, where it remains for months or even years (Wurl et al, 2013). Moreover, human activity has occurred in the studied oases for several centuries, and palms grow in orchards, where water is regularly supplied by irrigation.…”

“…In contrast, the La Niña phenomenon produces drought in northwest Mexico and rains in the South Pacific Ocean (Caso et al, 2007). Some authors have suggested that the rains that occur during the summer monsoon period are the main source of water to the water-bearing oases of Baja California Sur, followed by late summer Pacific hurricanes and tropical storms (Caso et al, 2007;Wurl et al, 2013) to maintain biodiversity and support human subsistence. Both periodic floods and droughts regulate the structure and composition of the plant communities in the oases (León de la Luz et al, 1997) and have been related to historical land use and the development of different economic activities in the oases (Cariño, 1996;Martínez-Ballesté, 2014).…”

“…Through the use of DEMs, geomorphological (Hutchinson et al 2001) and hydrological properties (Jarihani et al 2015) can be analyzed. These include soil moisture (Ludwig and Schneider 2006;Gao et al 2016), flood impact (Sanders 2007;Tarekegn et al 2010;Gichamo et al 2012;Yan et al 2014;Wurl et al 2014), soil stability, potential erosion, precipitation retention, channel shape, land depressions, etc. (Barnes et al 2014).…”

Water movement modeling in plain areas requires digital elevation models (DEMs) adequately representing the morphological and geomorphological land patterns including the presence of civil structures that could affect water flow patterns. This has a direct effect on water accumulation and water flow direction. The objectives of this work were to analyze, compare and improve DEMs so surface water movement in plain areas could be predicted. In order to do that, we evaluated the accuracy of a digital elevation data set consisting in 4064 points measured with a differential global positioning system (GPS) in a plain Several topographic attributes (i.e., height, surface area, land slope, delimitation of geomorphological units, civil structures, basin boundaries and streams network) and different interpolation methods were analyzed. The results showed that both the SRTM and the ALOS PALSAR DEMs had a ± 4.4 m root mean square error (RMSE) in contrast to the ASTER DEM which had a ± 9 m RMSE. Our analysis proved that the best DEM representing the study area is the SRTM. The most suitable interpolation methods applied to the SRTM were the inverse distance weighting and the ANUDEM, whereas the spline method displayed the lowest vertical accuracy. With the proposed method we obtained a DEM for the study area with a ± 3.2 m RMSE, a 33% error reduction compared to the raw DEM.
