Spinner Flowmeter

A methodology is developed for a new hydraulic characterization of continental hydrological basins. For this purpose, the division of wells into flow stretches with different hydraulic behaviour is made according to the results of the flowmeter, supposing the hypothesis hydraulic head of the deepest flow stretches of the well do not necessarily match the head showed by the overall well.
The data used come from a water-well located in a multi-layered aquifer that makes up the detrital continental basin of the Tajo River, in the center of the Iberian Peninsula. These data collect the results of the step-drawdown pumping test, and the flowmeter log data and the fundamental hydraulic parameters needed (Reynolds number, turbulence exponent, friction factor, …).
Two files are included in data base:
Flowmeter Results CNCP Well (raw-data).txt file shows Depth (m), Measured velocity, Reynold Number, Turbulence exponent, Mean velocity and Friction Factor values.
Step-drawdown pumping-test CNCP file shows STEP DRAWDOWN PUMPING TEST data: t (min), Q (ℓ/s) and z (m).

本研究开发了一种适用于大陆水文盆地的新型水力表征方法。为此，研究团队依据流量计测试结果，将研究井划分为具有不同水力特性的流动段，并提出假设：井内最深流动段的测压水头，未必与全井整体测得的水头相一致。

本次研究所用数据取自伊比利亚半岛中部塔霍河（Tajo River）碎屑型大陆盆地内多层含水层中的一口水井。该数据集涵盖阶梯降深抽水试验结果、流量计测井数据，以及所需的核心水力参数（雷诺数（Reynolds number）、紊流指数、摩擦因数等）。

本数据集包含两个文件：
1. 《CNCP井流量计测试结果（原始数据）.txt》：记录了深度（单位：米）、实测流速、雷诺数、紊流指数、平均流速及摩擦因数值。
2. CNCP井阶梯降深抽水试验文件：包含阶梯降深抽水试验数据，具体包括时间t（单位：分钟）、流量Q（单位：升/秒）及水头z（单位：米）。
