“…The DULQ was 53%, 48%, and 78% for the MN 2014, ND 2014, and ND 2015 (table 3). For a surface irrigation system, 70% DULQ is considered an acceptable value (Huffman et al, 2011). Our measurements showed the DULQ was below the acceptable range when the SI duration was short.…”

“…The SI system UC was close to the acceptable range (water was applied from below the surface). A sprinkler system is considered acceptable with a UC of 80% (Huffman et al, 2011). There was no observed difference in crop growth due to lower uniformity coefficient.…”

“…Essa distribuição foi ajustada às séries históricas de intensidades máximas de chuvas com 30, 360, 720 e 1.440 min de duração para estimativa dos valores associados aos tempos de retorno de 5, 50 e 100 anos. As combinações desses tempos de retorno e tempos de duração estão associadas às chuvas intensas mais frequentemente aplicadas ao dimensionamento de obras hidráulicas para controle da erosão e do escoamento superficial em estradas, áreas urbanas e rurais (Huffman et al, 2011).…”

RESUMOEstudos associados a chuvas extremas são constituídos de eventos de interesse prático para a gestão dos recursos naturais, como manejo de bacias hidrográficas e conservação dos solos e da água. A distribuição espacial desses eventos possibilita inferir sobre áreas onde sua ocorrência é acentuada e desprovida de informações técnicas. Os objetivos deste trabalho foram promover, a partir de dados pontuais de 177 estações meteorológicas e com a utilização de técnicas geoestatísticas, o mapeamento de chuvas intensas para o Estado de Minas Gerais e identificar as áreas mais vulneráveis no tocante à ocorrência dessas chuvas nesse Estado. Foi constatado que as maiores intensidades ocorrem nas regiões leste e noroeste de Minas Gerais, o que pode ser explicado pela maior influência da Zona de Convergência do Atlântico Sul, além de ocorrência de chuvas convectivas. Foi possível, também, constatar e mapear intensidades intermediárias nas regiões sul e central e os menores valores para as regiões norte e nordeste de Minas Gerais. Para maiores durações, verificou-se, para a região sul, ocorrência de altas intensidades, o que está associado à entrada com maior frequência de frentes frias, produzindo chuvas de longa duração.Termos de indexação: erosão do solo, chuvas intensas, semivariograma cruzado, cokrigagem.

“…where S is the maximum potential difference between rainfall and runoff at the moment of rainfall initiation and CN is a proportion of rainfall converted to runoff, adjusted for antecedent rainfall conditions. CN values were derived for Puerto Rico using the method described by [51], based on land use, hydrologic soil group, and antecedent rainfall conditions. To estimate DP, the following procedure is followed: SMD2 i = Precip -ET a -RO + SMD1.…”

A solar insolation satellite remote sensing product for Puerto Rico, the US Virgin Islands (USVI), Dominican Republic, Haiti, Jamaica, and Cuba became available in 2009 through a collaboration between the University of Puerto Rico-Mayagüez Campus and the University of Alabama in Huntsville. Solar insolation data are available at 1 km resolution for Puerto Rico and the USVI and 2 km resolution for the other islands, as derived from 500 m resolution GOES-16 visible imagery. The insolation data demonstrate the powerful utility of satellite-derived fields for water resource applications, specifically the routine production of potential and reference evapotranspiration. This chapter describes the theoretical background and technical approach for estimating components of the daily water and energy balance in Puerto Rico. Useful information can be obtained from the model, which benefits disaster and emergency management, agriculture, human health, ecology, coastal water management, and renewable energy development at the island scale.
