“…En este contexto, el modelamiento hidrológico se convierte en una herramienta poderosa para desarrollar escenarios que proporcionen alternativas de gestión sostenible de los recursos hídricos (Paul et al 2021). Por lo tanto, se han desarrollado una amplia variedad de modelos hidrológicos para una extensa serie de procesos medioambientales a distintas escalas espaciotemporales (Zhang et al, 2020;Zhang y Chiew, 2009;Bai et al, 2020;Paul et al, 2021;Nagdeve et al, 2021). Cada modelo tiene sus propias características y utiliza diferentes parámetros para proporcionar un mejor ajuste (Martínez-Austira, P. y Patiño-Gómez, C., 2012).…”

Los modelos hidrológicos son herramientas esenciales para la planificación y gestión de los recursos hídricos y del medio ambiente. En las últimas décadas se han desarrollado diversos modelos hidrológicos, cada uno con características y parámetros específicos, con el objetivo de representar mejor la microfísica del ciclo hidrológico, aunque, algunos investigadores han encontrado que incluso el uso de técnicas complejas de modelamiento no garantiza una mejor evaluación, debido a la heterogeneidad del suelo y al cambio climático que desempeña un papel determinante en el comportamiento del régimen hidrológico. En este artículo, se presenta un breve resumen de once distintos modelos hidrológicos, ocho de libre acceso. Los modelos incluidos corresponden al modelo de capacidad de infiltración variable (VIC), TOPMODEL, HBV, MIKE SHE, herramienta de evaluación de suelos y aguas (SWAT), HSPF, VELMA, PIHM, KINEROS, WEAP y HEC-HMS. Considerando aspectos como la región de aplicación, escala espacial, datos de entrada y si la interfaz es amigable e intuitiva, se concluye que el modelo SWAT seguido de los modelos HEC-HMS y WEAP son los más versátiles y adecuados para ser aplicados en regiones como Nicaragua. Este estudio proporciona una guía a los modeladores para identificar el tipo de modelo hidrológico que podrían aplicar en una cuenca específica para resolver un problema determinado, así mismo, les permitirá determinar la viabilidad de uno con respecto al otro según la disponibilidad de datos de entrada que se requieran y los recursos disponibles tanto informáticos como financieros.

“…The contour terraces aimed to decrease water leakage out from the system (Kumar et al, 2020; Rahmati et al, 2022), and may reduce the soil erosion. The potential of this method is high and may prevent, based on the previous studies, runoff leakage by up to 90% and groundwater recharge by 45% (Nagdeve et al, 2021). Several parameters determine the hydrological functioning of the contour terraces and the resulting agricultural utilization, including the native area soil type, geographic outlines (incline and drainage area width), runoff potential, slope patterns, and net drainage (Kolekar et al, 2017; Nagdeve et al, 2021).…”

Each contoured terrace is hydrological correlated with its' upper and lower ones by a sloppy riser, such as in the northern highlands of Rwanda (Kagabo et al, 2013) or a dike, which is mainly constructed in arid and semiarid regions worldwide, such in Tunisia (Al Ali et al, 2008), Southern Israel (Stavi et al, 2015), Spain (Pijl et al, 2022), Ethiopia (Mesfin et al, 2018), and Northern China (X.

Trenched and diked contours for sustainable agricultural utilization in changing world; soil hydrological, geomorphological, and physical perspectives from over 70 years of implementation in the Northern Negev

Trenched and diked contours (TDC) are used in hilly arid regions worldwide to reduce runoff and soil erosion. The TDC is based on three parts: ‘runoff contributing area’, trench, and adjacent soil dike on the hillslope contours. Surveys over the Northern Negev indicate the hydrological interrelation between the inter‐dike surface and the dike. This study hypothesized that all the TDC parts are hydrologically interrelated. The objective is to analyze the soil's physical properties that influence the interrelation from dike construction until maturation and the influences of these interrelations on soil fertility, salinity, and stability. TDC systems, also known as ‘Shikim’, were constructed by the KKL‐JNF (Karen Kayemet L'Israel. The Jewish National Foundation) all over the hills of the Northern Negev, the semiarid region of Israel, from the 1950s until present, which gives the ability to analyze the dynamic of water flows inside the TDC s along their existence. The findings indicate three hydrological interrelations, (i) From the ‘runoff contributing area’ into the trench, which differs between the planted and un‐planted types; (ii) From the trench into the dike; (iii) and water migration in the ‘dike’ medium. Along the TDC maturation, the intensity of biological influences on these interrelations increases, leading to increased water mobilization to the trench (planting strip) and into the dike medium. The water migration in the ‘dike’ leads to forming of a soil bed adequate for sustainable agricultural utilization in its' downslope face. The finding of this study will maximize the agricultural utilization of the TDCs and their profitability.
