POTENCIAL DOS RECURSOS HÍDRICOS A PARTIR DA INTENSIDADE E DISTRIBUIÇÃO DA ENTROPIA DA PRECIPITAÇÃO PLUVIAL E AGRUPAMENTOS NO ESTADO DO PIAUÍ
Abstract
O objetivo deste estudo é definir, com base na teoria da informação da entropia de Shannon, métricas para representar a aleatoriedade da intensidade e da ocorrência da chuva mensal e, em seguida, avaliar a disponibilidade potencial de recursos hídricos (DPRH) do estado do Piauí. Aqui a entropia é expressa no contexto de probabilidade de ocorrência da intensidade de variáveis hidrológicas, isto é, no contexto da estrutura da IE. Os resultados mostraram que a parte oeste possui os melhores valores de intensidade e densidade de entropia, com chuvas perenes e mais abundantes, enquanto que o lado leste e sul apresentaram valores negativos, com chuvas concentradas no tempo e baixa oferta. Os agrupamentos identificaram subdivisões dos níveis de recursos hídricos no Piauí, mostrando os postos com déficit, áreas de transição e com melhor potencial. Em geral, o vale do rio Parnaíba se mostrou propício para a produção de inúmeras culturas.Downloads
