Design of water control structures, reservoir management, economic evaluation of flood protection projects, land use planning and management, flood insurance assessment, and other projects rely on knowledge of magnitude and frequency of floods. Often, estimation of floods is not easy because of lack of flood records at the target sites. Regional flood frequency analysis (RFFA) alleviates this problem by utilizing flood records pooled from other watersheds, which are similar to the watershed of the target site in flood characteristics.
Clustering techniques are used to identify group(s) of watersheds which have similar flood characteristics. This book is a comprehensive reference on how to use these techniques for RFFA and is the first of its kind. It provides a detailed account of several recently developed clustering techniques, including those based on fuzzy set theory and artificial neural networks. It also documents research findings on application of clustering techniques to RFFA that remain scattered in various hydrology and water resources journals.
The optimal number of groups defined in an area is based on cluster validation measures and L-moment based homogeneity tests. These form the bases to check the regions for homogeneity.
The subjectivity involved and the effort needed to identify homogeneous groups of watersheds with conventional approaches are greatly reduced by using efficient clustering techniques discussed in this book. Furthermore, better flood estimates with smaller confidence intervals are obtained by analysis of data from homogeneous watersheds. Consequently, the problem of over- or under-designing by using these flood estimates is reduced. This leads to optimal economic design of structures. The advantages of better regionalization of watersheds and their utility are entering into hydrologic practice.
"A soul must search with blinded eyes For that which can't be seen. It senses yearnings deep within, Yet knows not what they mean."-L.L. Culpepper
A full range of human emotion and experience is captured beautifully and poignantly in L.L. Culpepper's debut book of poetry A Surrendered Soul, Like Water. As a writer, Culpepper uses her words to bring meaningful expression to the often indescribable ruminations of the heart and to the hardships we encounter along life's journey. And whether she is mining the depths of despair, reminding us of the fragility of life, or speaking of surrender and salvation, she does so with the utmost sensitivity, using her carefully chosen words to bring clarity and comfort. The scriptures that accompany many of the poems provide a spiritual context to the poet's contemplations, and offer a hopeful perspective on how God works patiently through our struggles, confusion, hurts, fears, and even failures to create purpose and new beginnings. In A Surrendered Soul, Like Water Culpepper has accomplished the aim of many poets and artists: to express deeply personal thoughts and experiences in a universal way that reaches other human beings. It's the kind of poetry you will find yourself returning to repeatedly, sharing with others, and relating to in new and profound ways at various seasons of your life. - Allison Malafronte, editor
"In the pages of this book, my poetry speaks of things that most of us think about on some level but have difficulty putting into words. My hope is to give readers the gift of honesty - and to encourage them to look deeper, to seek the truth, and to know that they are not alone in this journey." - L.L. Culpepper
