If you already have a bad scan, here is a quick technical fix without downloading unknown software:
This DIY method is safer than downloading a pre-made "fixed" file which might contain malware.
Before downloading any file, it helps to know what you are looking for. The book is structured into 15 chapters plus appendices. A "good fixed PDF" will have all of these intact.
A detailed feature looking at open channel flow, possibly as discussed in Madan Mohan Das's work (assuming it's available in PDF format), might cover:
Search for the word "Manning." In a true fixed (clean OCR) PDF, it will find every instance. In a bad scan, it might find "Manninq" or nothing at all.
Do not waste time on corrupted 10 MB scans. Instead:

Open Channel Flow by Madan Mohan Das is a foundational textbook for undergraduate and postgraduate civil engineering students, providing a comprehensive analysis of fluid motion with a free surface. First published in 2008 by PHI Learning, the book bridges the gap between theoretical fluid mechanics and practical hydraulic design. Core Concepts and Hydraulic Principles
The text defines open channel flow as the gravity-driven movement of liquid (usually water) where the surface is exposed to atmospheric pressure. Unlike pipe flow, which is driven by pressure gradients, open channel flow is governed by the channel's slope, shape, and roughness.
Das organizes the complex physics of these systems into several key thematic areas:
Fundamental Equations: Covers continuity in 1D and 3D, velocity distribution, and the types of forces acting on the flow.
Uniform and Varied Flow: Explores steady uniform flow (where depth remains constant) versus gradually varied flow (GVF) and rapidly varied flow (RVF).
Energy and Momentum: Detailed analysis of specific energy, critical depth computation, and the specific force curve.
Hydraulic Structures: Practical sections on hydraulic jump, energy dissipators, and the design of alluvial channels. Advanced Topics and Computational Tools
A distinguishing feature of this work is its focus on modern computational methods. It includes computer programs specifically designed to solve steady gradually varied flow equations.
Flood Routing: The text concludes with an examination of Saint-Venant equations and numerical methods for flood routing and dam-break simulations.
Unsteady Flow: Detailed treatment of the unsteady equations of continuity and dynamic equations for complex flow scenarios. Open Channel Flow | PDF | Foreign Language Studies - Scribd
